1993 Chevrolet Camaro Security Light No Start Fix
Hey michelle,
The security light flashing means either a fault in the system or is in theft mode. Was the ign switch and key a "matched set"? That is crucial! If it was then there may also be an issue with the security module. If you or your hubby need the dianostic test or wiring diagram, let me know and will drop you it in a email.

Sorry, meant to say the ignition lock cylinder and key have to be a matched set as they send the electrical signal to the anti-theft module/pcm to enable starting. There has been an issue with the lock cylinder wiring breaking after age and causing that condition.

Michelle,
2 choices. 1. Take the vehicle to a trusted shop and get an accurate diagnosis and fix. 2. You can do the lock cylinder. To do this yourself, 1st I'll send along the repair procedure. 2nd, contact your local GM dealer, explain to them that you need a new lock cylinder and key ( you may need to give them the vin #), they may also need to examine/test your key for the proper resistance value(yes! there is a tiny resistor in your key) and get the proper parts. The replacement of the cylinder isn't too hard a job if you follow the procedure! Check your email and let me know if you need any assistance!

Chris[/quote:2940a18570] I got the lock cylinder and key but the key is a normal key unlike the key that came with the car the guys at the parts store said it bypasses the anti theft system is this true are they just feeding me a line ?
Sounds like the parts person is a bit off base. Unless its an aftermarket security system, then his bypass is out the window! Simplified .... the key and cylinder send a signal to the pcm, if the signal is the correct one programmed into the pcm then it will allow the car to start, if not ..... then no go! I recommend you return the part and get one from the dealer with the correct setup!

Glad to hear the camaro is back on the road! Have hubby post here. pm me or email me and we'll see if we can get his truck up to par!

Suggested Repair
Use a matched ignition lock cylinder and key with the correct resistor value so the anti-theft module and PCM receive the proper start-enable signal. A plain parts-store key will not bypass the factory system. Have a GM dealer or locksmith match the cylinder to the original key, and also check the lock-cylinder wiring, which can break with age.
Conversation Summary
A 1993 Chevrolet Camaro V8 suddenly would not crank, with dash lights on and the security light flashing. The clutch switch, ignition switch, starter, battery, and a worn key had already been addressed. The expert explained that the lock cylinder and key must be a matched set that sends the correct resistance signal to the anti-theft module and PCM, and that aged cylinder wiring can fail. A plain bypass key was rejected. The owner had a locksmith match the original key to a new cylinder, and the Camaro then started. A separate 1998 Dodge Ram idle-stall question was raised but not diagnosed.
